title: Aneuploidy patterns in Drosophila melanogaster.
abstract: By using an appropriate scheme, various combinations of losses and gains of chromosomes I and II arising in oocytes of Drosophila melanogaster were obtained. The frequencies of these combinations can be arranged as special sequences or patterns which we call "aneuploidy patterns." Aneuploidy patterns were established for spontaneous, colchicine-induced, and X-ray-induced exceptions and were shown to be highly specific for the agent tested. Such patterns can be obtained very quickly, because only exceptional progeny survive. By establishing aneuploidy patterns for chemical agents one would get information of the "aneuploidizing" action of the compounds tested.
